Abstract: Digital beam forming consists of the spatial filtering of a signal where the phase shifting, amplitude scaling and adding are implemented digitally. The idea is to use a computational and programmable environment which processes a signal in the digital domain to control the progressive phase shift between antenna elements in the array. Digital beamforming allows several attractive features in the performances of communication systems. The main advantage to be gained from digital beamforming is greatly added flexibility without any attendant degradation in signal-to-noise ratio (SNR).This research presents the design and simulation of a low cost Digital Beamforming (DBF) antenna. This DBF antenna can form part of the antenna structure in the receiver of the base station of a wireless communication system. The uniform amplitude weighting function is the beam pattern synthesis considered for the beam formation. The simulation is done in MATLAB.
Keywords: Beamforming, Antenna array, phased arra

Abstract: The attribute reduction is one of the key processes for knowledge acquisition. Some data set is multidimensional and larger in size. If that data set is used for classification it may end with wrong results and it may also occupy more resources especially in terms of time. Most of the features present are redundant and inconsistent and affect the classification. In order to improve the efficiency of classification these redundancy and inconsistency features must be eliminated. This paper discusses an algorithm based on discernibility matrix and Information gain to reduce attributes.

Abstract: Fukui’s conical cup test is the one of the formability characteristics evaluation for various sheet metals. The formability characteristics such as diametrical ratio, maximum drawing load, depth of cup up to fracture are to be evaluated. This test is related to drawing test. This test can be performed by using parameters such as friction, process parameters and without blank holder. In fukui’s conical cup drawing test a single specimen with dimensions drawn into conical cup until the fracture is occurred at the bottom of cup by help of flat cylindrical punch and without using the blank holder. The base diameter of fracture conical cup is used to determination of diametrical Ratio. The diametrical ratio is the ratio between base diameter of fracture of conical cup with respect to outer edges of cup to original blank diameter. This indicates formability of sheet metals through this test. So formability can be represented as formability index. Hence the formability index expressed as diametrical ratio.The smaller the value of diametrical ratio the better is the formability of sheet metal as per fukui’s test. In this test the formability characteristics of sheet metals such as alloys of aluminum alloy, mild steel alloy and cartridge brass are studied through finite element analysis.
Keywords: formability, drawing, diametrical ratio, maximum drawing load.

Determining Hysteresis Damping in a Steam Turbine Blade using a Finite Element Tool

Abstract: Damping is a phenomenon by which mechanical energy is dissipated, usually converted as a thermal energy in dynamic systems. The damping caused by friction between the internal planes that slip or slide as the material deforms is called hysteresis damping or material damping. This paper deals with determining hysteresis damping of a typical turbine blade. The damping is quantified as a function of strain amplitude. ANSYS and Hyper Mesh are adopted for necessary calculations. First the natural frequencies and orthonormal mode shapes are obtained at the desired speed. Lazan’s damping law is used to determine the specific damping energy in each element of the blade. Total damping energy and strain energy are calculated by integrating them over the entire volume. With the help of these the loss factor is obtained. From the loss factor, the equivalent viscous damping ratio is determined. Procedure for one mode shape is shown.

The Mathematical Aspects in Art to Create Decorative Effect in Design Patterns

Abstract: Educational data mining is current growing research area and the main essence of data mining concepts are used in the educational field for extracting useful information of the students based on their behavior in the learning process. Prior approaches used decision tree classifications optimized with ID3 algorithms to obtain such patterns but discovering the implicative tendencies is valuable information for the decision-maker which is absent in tree based classifications. So we propose to use outlier detection for mining and evaluating educational data of students. In this paper, outlier detection mechanisms are used for identifying outliers which improve the quality of decision making. We used outlier analysis to detect outliers in the student data. In proposed system, clustering mechanism along with univariant analysis is implemented. Clustering is finding groups of objects such that the objects in one group will be similar to one another and different from the objects in another group. While clustering, the large data set is divide into clusters which consists of outliers. After Clustering, the data points which are present outside the clusters are identified and treated as outliers. Identification is done by using univariate analysis which is the simplest form of quantitative (statistical) analysis. A basic way of presenting univariate data is to create a frequency distribution of the individual cases Here, we analyze the performance of UG students of our college and present the results using outlier detection mechanism. The analyzed results are represented using histograms which are based on univariate analysis.
Keywords: Outlier, Clustering, Univariate analysis, and Histograms.

Abstract: In the case of vehicles, the term chassis means the frame plus the running gear like engine, transmission, driveshaft, differential, and suspension. An all-terrain vehicle (ATV), also known as a quad, quad bike, three-wheeler, or four-wheeler, is defined by the American National Standards Institute (ANSI) as a vehicle that travels on low pressure tires, with a seat that is straddled by the operator, along with handlebars for steering control. As the name implies, it is designed to handle a wider variety of terrain than most other vehicles. This paper deals with design of chassis frame for an All Terrain Vehicle and its Optimization. Various loading tests like Front Impact, Rear Impact, Side Impact, Roll over test etc have been conducted on the chassis and the design has been optimized by reducing the weight of the chassis.

Abstract: The success of a company often depends on the continued, safe and productive operation of rotating machinery. An effective maintenance program is vital to this kind of success. The quality of company’s maintenance program determines how long the machines will run, how safe they are for the people working around them, and how productive the machine will be. Berar these things in mind while you consider the following benefits of a CBM program in greater detail. The operation and maintenance of high valuable machines is very important in increasingly stiff global market and requires that it provides maximum return on investment with minimum maintenance costs. Improving plant efficiency by implementation of latest techniques in maintenance can lead to significant savings with improvement in overall operating efficiency of plants. This project brings outs the importance of vibration analyzing in maintaining the machines. The vibration analysis can be simplified and make time saving by analyzing the FFT (Fast Fourier transform) or amplitude vs. frequency spectrum. By analyzing the spectrum we can estimate the cause of vibrations in the machine.

Abstract: Bandwidth management is one of the most widely misunderstood subjects in modern networking. Bandwidth Management is a lot like economics, because the complexities of how it works are beyond simple logic. Internet "bandwidth" is not a spectrum; traffic streams are one bit at a time. Bandwidth on the internet can only be conceptualized over time, and the amount of time that you talk about can greatly change the user experience. For reliable data transmission within computer network and internet forms the basis for management and control of bandwidth. Without bandwidth management, an user will not be able to handle all available bandwidth on the networks. It will be impossible to differentiate between various network traffics, and it will also be difficult to control which user or application has priority on the network. Applications which require specific quantity and quality of service may not be predicted in terms of available bandwidth, thus making some applications run poorly due to improper bandwidth allocation. This work focus on the development of an application to combat the challenges facing easy flow of data transmission problems in network design as organization network evolves. Here PHP Script, Apache Server and MySQL are the development tools used

Abstract: Laboratory experimentation was carried out to analyze the performance of M25 concrete made by partially replacing aggregates with waste materials like construction debris, PVC scrap and leather waste. The resultant concrete was tested for parameters like weight, compressive strength, slump and workability and compared with conventional plain cement concrete. It has been observed that the use of waste materials results in the formation of light weight concrete. There is a considerable increase in the compressive strength of concrete when the coarse aggregates are fully or partially replaced with construction debris. However a minor reduction in workability of the concrete mix was observed. When the coarse aggregates were replaced with PVC scrap in small percentage by weight, the resultant concrete shows fair value of compressive strength and the workability. But with the partial introduction of leather waste in place of sand in concrete, the concrete passed workability test but it failed completely in compressive strength test and gave almost zero strength. Hence, except leather waste other materials like construction debris and PVC scrap performed well as full or partial replacement for concrete aggregates and can find suitable application in construction industry as alternative to conventional materials. Uses of such waste materials will not only cut down the cost of construction, but will also contribute in safe disposal of waste materials. Apart from the environmental benefits, the addition of such wastes, also improves certain properties of resultant concrete.

Electrical Characteristics of Micro-Hydro Power Plant Proposed in Valara Waterfall

Abstract: The most important problem faced by a country like India is that of rural electrification. This paper proposes a permanent magnet synchronous generator (PMSG) based micro power plant, which is used for a standalone micro hydro power generation. The prime mover of the system is the hydraulic turbine, essentially a pelton wheel turbine in this proposed scheme. The power produced can be directly given to the load Centre, which is within 200 m radius of the generation site. In this paper we are considering a constant output power from the turbine system which drives the alternator. The detailed economic assessment of the power produced is also analyzed in this paper.

Cost of Quality as a Driver for Continuous Improvement - Case Study – Company X

Abstract: In the manufacturing, metal casting industry is one of the oldest basic principal and most important industries. The casting process is hindered by the occurrence of various defects. High casting reject levels and customer returns have a considerable adverse effect on productivity, delivery performance, customer satisfaction and employee morale. In addition excessive rejection reduces yield, wastes valuable raw materials and involves management time in problem solving. All foundry processes generate a certain level of rejection that is closely related to the type of casting, the processes used and the equipment available. This paper seeks to establish the extent to which cost of quality can impact on continuous improvement of the products and the relationship with the customers of the organization. To determine the cost of quality (COQ) at casting company X, the researchers used existing company records, publications and historical evidence of the company. The researchers utilized techniques such as, bar charts and tables in presenting and interpreting data. The above techniques have the ability to provide methods for collecting, presenting, and analysis and meaningfully interpret data. The research findings estimated the COQ to be 6.6% of sales revenue.

Performance Evaluation of OSPF-Based Data Network

Abstract: The implementation of the Open Shortest Path First (OSPF) Routing Protocol for data network has became imperative as the size of the internet growing at an alarming rate and data network needs to employ Routing Protocol to route data faster so as to prevent network congestion and high IP drop across a data network. The Open-Shortest Path First (OSPF) protocol, due to its use of route cost as its metric provides better scalability than rival protocols and a reasonable convergence time. We investigate the performance of OSPF routing protocol in a WLAN. This is done with the help of OPNET IT GURU 9.1, in which six scenarios were simulated for the throughput, delay and IP Traffic dropped for both OSPF and RIP. The result showed that network performance was enhanced by a 50-150% range when the OSPF routing protocol was used instead of Routing Information Protocol (RIP).
